Hi,

In one school I have a Dell PE2950 with 4 gig of Ram that locks up. We had problems with this server locking/abending back in June. During down time over the summer we upgraded to NW65SP7 hoping that would help our problems. All summer while staff and students we away everything worked well. No problems imaging machines and summer maintenance. When staff & students returned and there was again 400+ users on the network at any one time we have had 2 server lockups already. When it locks there is no warning just loss of connectivity by users and the server console is locked solid. We have to power off the server and restart. It is then good for a couple of days (useally) and it will do it again. Following is the abend log from this morning. (Full file is attached)
